I'm testing Bifrost on https://bifrost.tst.fucine.it/ and when I try to import any demo I see:

So it seem that our server is not able to get this: https://neuronthemes.com/bifrost/demo-importer/homepages/classic/classic-agency.xml
In fact:

This is kinda annoying. Any way to have that import utility to properly working?

[...]

Perhaps this could depend on mod_security being in place:

[Fri Jul 16 11:29:02 2021] [error] [client 5.89.102.31] ModSecurity: Warning. [Rule: 'REQUEST_FILENAME' '!@pmFromFile path_excludes'] [id "77140992"] [msg "IM360 WAF: Suspicious access attempt (WP folders)!||SC:/home/tstfucine/subdomains/bifrost/wp-admin/options.php||T:LITESPEED||REQUEST_URI:/wp-admin/options.php||"] [severity "NOTICE"] [tag "service_i360custom"] [tag "noshow"] [hostname "bifrost.tst.fucine.it"] [uri "/wp-admin/options.php"], referer: https://bifrost.tst.fucine.it/wp-admin/options-general.php

Let me disable the 77140992 rule ID for that domain, and I'll be back to you soon after.

Thanks, e.-

Nope, neither after having done that:

Rebuilding and restarting Apache:
Built /etc/apache2/conf/httpd.conf OK
[OK] Send SIGUSR1 to 515487
..Done

As per:

Still getting this:

Any idea? Thanks, e.-

From https://neuronthemes.ticksy.com/ticket/2824585/I got this:

2) Save the file from main-demo.xml and go to Dashboard > Tools Import and import the file manually(XML file).

So I did it:

Seems to have worked. Anyway: is there a way to fix this from your side?

Thanks, e.-

I've restored the site from an Installatron backup.

And nope: WooCommerce was already installed, as per (taken after restore):

There are only updates, but those 2 plugins were already installed:

Going to revert back site to latest snapshot.

Thanks, e.-

Not a problem. Not at all. The one we're referring to is just a test environment. The real site - the one I'm developing with Bifrost - is hosted elsewhere, and not publicly accessible. In the end the import process worked as suggested in that other ticket, and that was all we need. All the best, e.-

No need at all. That site is sandbox/staging/testing. It might be live burned and I wouldn't miss a single bit of it.
I'll use it only for allowing you to see what I see in real developing site, after having exported there and imported here. Anyway I will pass you, sooner or later, the info on local DNS resolver override (/etc/hosts), so that you can see what is actually happening in real/development site, under the "fucine.it" domain. And we're talking about a MS/MU WP setup, anyway. This way there wouldn't be any need of using https://bifrost.tst.fucine.it/ as interchange. For your records: in that production VPS the data/demo import utilities work perfectly.
Cheers, e.-
